PETER SWEENEY, OF NEW YORK, N. Y.

DUST-GUARD FOR CAR-AXLE BOXES.

SPECIFICATION forming part of Letters Patent No. 379,524, dated March 13, 1888.

Application filed July 14, 1887. Serial No. 244,288. (No model.)

`New York, have invented certain new and useful Improvements in Dust-Guards for Cars; and I do declare the following to be a` full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to makea dust-guard for the journals of car-axles, so that it will hug the lower side of the journal, take up wear automatically, and be easily replaced.

Figure l oi' the drawings is a vertical section of mydust guard; Fig. 2, a detail View in front elevation of the two parts of the stirrup; Fig. 3, a detail in elevation ,of one of the parts ofthe cap for the springs, and Fig. 4. is a horizontal section of Fig. 3.

In the drawings, A represents the guard divided on a horizontal diametrical line into two equal and similar parts, so as to nearly but not quite close around the car axle journal, the same being made of wood, which is cheap and easily replaced. 1 At the middle of the bottom of the lower section I make the notch or eX- cision a, in which iits the upwardly-projecting studs b b of the two part stirrup B. Each part of the stirrup isprovided with a rabbet, b', to receive the guard and a rounded top, b2, with a head, bi, for the spiral spring O. Over the rounded tops and springs G, I use the cap D, which is made of two similar parts with the end boxes, l d, and connecting -plates d d'. The two boxes being fitted over the springs, as shown in the drawings, the plates are conupward tension of the springs C G raises the stirrup B, so as to make the guard yieldingly hug the lower part of the journal and automatically take up wear, while either half of the guard may be quickly detached and replaced when necessary.

lt will be observed that one of the ends of the springs C rests againstV the head b5, while the other is supported on the capshelfb.

In practice my dust -guard is found to be very efficient, not expensive, easily attached or removed, and requiring little attention to keep it in lworking order. I

Having thus described all that is necessary to a full understanding of my invention, what I clainras new, and desire to protect by Letters Patent, is-

l. A car-axle dust-guard having the upper and lower section hung in the same stirrup, the latter being pulled upward by a spring, and thus causing the lower section only to hug the axle-j ournal, as described, and for the purpose specified.

'2. The stirrup made in two parts, each having a bottom stud, b2, a rabbet, b', anda rounded top with head b3, whereby it may be used, as described.

3. The combination, with the two-part stirrup having heads bp5 b3 and the spiral springs O C, of the two-part cap D D', having the shelf b4, whereby the springs may be readily inserted and protected, as specied.

In testimony whereof IaftiX my signatn re in presence of two witnesses.
